Yes, I think that if you have a modules floppy with the proper mods you
will be able to get things working, with LVM. I've never tried it though,
you might want to mail the suse support list (I rarely do fancy installs
any more, I just want a basic machine to code on ;-)

For some reason, reiserfs beats up on a bottleneck in LVM, and you see
this more with O_SYNC writes (reiserfs O_SYNC is faster without LVM). But,
it sounds like andrea and the LVM guys are working on it, so I don't expect
it to be a problem much longer. The transaction tracking patch I just
posted will help too, much more than any LVM changes.
